14 Claims. (Cl. 24-205) This invention relates to separable fasteners employing stringers having scoops arranged along one edge thereof for coupling the stringers together. More particularly the invention relates to a scoop construction of the double acting type wherein the coupling portions of the scoops have laterally ofiset'coupling elements producing on the resulting coupled stringers a better seal between adjacent links and additional strength in resisting stress or strains to which the coupled stringers may be subjected.

The novel features of the invention will be best understood from the following description when taken together with th accompanying drawing, in which certain embodiments of the invention are disclosed, and in which the separate parts are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a plan view of a part of two stringers, illustrating two sliders thereon and showing my improved scoop construction. v

Fig. 2 is a face view of two scoops showing a part of the scoop of one stringer in section.

Fig. 3 is an enlarged section on the line 3-3 of Fig. 2 with both scoops in Fig. 2 shown in full.

Fig. 4 is an edge view of one of the scoops, and

Fig. 5 is a view similar to Fig. 4, showing a modification.

In referring to double action scoops for separable fasteners of the kind under consideration, ref erence is made to scoops of the type and kind facilitating coupling and uncoupling by sliders arranged in either of two possible positions on the stringers and movable thereon to couple and uncouple the same. This type of scoop construction materially simplifies the production of stringers of the kind under consideration,'and in addition to the use of single sliders of coupling and uncoupling the stringers, the double action scoop structure also permits of the use of two sliders movable on a pair of stringers.

In Fig. l of the drawing, 10 and H illustrate a small portion of two separable fastener stringers, and 12 represents the scoops spaced along one edge of each stringer. At l3 and I4 is indicated two sliders movable along the stringers l and H in coupling and uncoupling the scoops l2. In the present illustration, the sliders l3, I4, have their narrow ends I directed toward each other, and

. theirwide diverging channel ends I6 arranged in opposite directions. In other uses, the wide ends I6 are arranged adjacent on the stringers.

Each scoop l2 comprises a mounting end portion I], apertured as seen at Is to receive the beaded edge of the stringer tapes in the cus- -Fig. 2 of the drawing.

tomary manner, and. at I9 is shown the coupling end portion of the scoop having, as clearly seen in Figs. 2 and 4 offset coupling sections 20 and 2|.

The edges of the sections 20, 2| inwardly of the projections 22-25 have substantially V- shaped notches 26, 21, and 28, 29 respectively. The notches 26 and 2! of the scoop of one stringer are adapted to receive the projections 25, 24 of the scoops of an opposed stringer, whereas the notches 28 and 29 are adapted to receive the projections 23, 22 of said last mentioned scoops.

As all scoops are of the same construction, the brief description of one will apply to all.

When the scoops of opposed stringers are coupled together, the angular sections identified by the reference numeral 30 in Fig. 2 of the drawing overlap in forming means keying the coupled scoops against transverse separation, that is to say, when subjected to a strain on the flat side surfaces of the scoops. These overlapped portions produce 'on the resulting fastener a more perfect seal between the coupled stringers than is usually customary. Further, this overlapping of the wall sections 30 produces a stronger coupling engagement between the scoops than is usually experienced.

In the construction shown in Figs. 1 to 4 inelusive, the sections 20, 2| are separated along a common line 3|, note Fig. 4 of the drawing. In Fig. 5 is shown a slight modification wherein coupling sections 32, 33 similar to the sections 20, 2| are separated by a narrow slot or aperture 34. At a predetermined point between the opposed surfaces of the slot 34, the sections 32, 33 are joined by a transverse pin portion 35, which is arranged within the outer boundary walls of both sections 32, 33.

In forming the scoops by die casting machines, the slots or apertures 34 will be formed by the use of suitable core members, as will also the pin portions 35. In such cases, these pin portions will unite the sections 32, 33.

By spacing'the sections 32, 33 one from the other, coupling of the scoops of opposed stringers is facilitated, particularly from the standpoint of alining the scoops. 0n the other hand, this spacing will also provide in the resulting fastener a greater flexibility between the coupledscoops,

permitting freer bending of the fastener than would be the case where surfaces as at 3| are in common abutting alinement.

The scoops as disclosed have mounting end portions engaging the tape or other support and coupling end portions. The coupling end portions may be said to be divided into offset sides, each side terminating at its outer end in a substantially hexagon head inwardly of which opposed edges of the coupling end portion have V-shaped recesses and the heads and recesses of each section being in staggered relationship, due to the offset arrangement of said sections. The coupling end portion of the scoops may also be said to have two projections and two recesses at each opposed edge thereof, with the projections and recesses on each edge offset with respect to each other.
